Not since “Double Dick Dude” has the Reddit community been so fascinated with one man’s penis.

After sustaining a spinal cord injury five years ago, Reddit user titantool received good news and bad news: He would still be able to walk, but he suffered partial paralysis in his bowel, bladder, and penis.

“I was in ICU for just over a month,” titantool shares in a comment, “and I remember when I first started to come around, I was feeling my penis and couldn’t feel it. I couldn’t comprehend and make the connection that it was dead.”

Before the accident, titantool had an “amazing” sex life with his girlfriend—but after, the couple’s ability to remain intimate “was really affected and nothing was working.”

So he started reading up on penile implants.

“I was on forums for a year talking to different guys,” he writes in a comment, “and they unanimously said how it was the best decision of their life.”

After a year on the fence and three cancelled surgical appointments, titantool writes that he finally underwent penile implant surgery at a University of Arkansas hospital.

Now 40, married, and sexually active once again, titantool stopped by Reddit to answer questions about his life and penis in a two-day AMA (Ask Me Anything).

Despite the fact that only “a few close friends” are aware of his surgery, he shares in a comment that he “want[s] to tell more men [about penile implants] because sexual dysfunction is a real thing.” To start a truly open dialogue, he posted a gallery of dick pics—before and after his surgery—and waited for the questions to roll in.

How Does the Device Actually Work?

If you’re not familiar with penile implants (or “bionic penises”), they can be a little confusing—particularly the mechanism they use to help men achieve an erection.

Reddit user titantool

“I meant to put a picture of the device in the album. I’ll do that now. To answer your question though, there is a pump in my scrotum that I can squeeze. It sends fluid to the chambers to make the penis erect. On the bulb/valve, I can squeeze a certain direction and the saline drains back into the reservoir,” titantool says. “Before implants, men had rods and they were basically permanently erect. Now, I can be flaccid or erect whenever I want. I can keep erect for as little or as long as I like.

And as titantool explains in another comment, the pump is located “in the bottom of [his] scrotum kind of between the 2 testicles,” which allows him to “squeeze this bulb that is pumping saline from a reservoir near [his] pubic area into these 2 tubes in [his] penis.”

"Inside there is the pump and valves. I have no feeling here so it isn't painful." (Reddit user titantool)

What Does It Look Like During the, Umm, Pump-up Phase?

Many redditors wanted to see the inflation in action. Titantool didn’t have an original video handy, but he shared a link for anyone curious and brave enough to click:

“Here is a video of how it inflates (not me),” he adds. “You can find other videos of how they put it in but it’s pretty gnarly.”

Did His Penis Change Size and Shape?

What Does His Wife Think?

Redditors wanted to know how the implant affected titantool’s relationship with his then-girlfriend, now his wife—a question he tackled piece by piece.

When user thisismymoniker asked what she thought of his reduced length and increased girth, titantool wrote, “I actually really liked how my penis looked before. I don’t think it looks as good, but wifey says the girth is fantastic and it feels better to her.”

But what about his balls?

“She says it feels weird. I agree. It took me quite a while to get over that feeling of a third ball in my scrotum. It’s avery unique feeling to it. It has texture so you can hang on to it better when inflating. It’s firm but squishy though and not hollow feeling. It only feels hard when the tubes are full of saline and you can’t squeeze anymore in there.”

Can He Orgasm, Ejaculate, and/or Feel Anything Down There?

His wife may be satisfied, but what about titantool’s sense of pleasure?

Again, this proved to be a complex question with counterintuitive answers—because titantool can achieve orgasm, but completely lacks sensation in his penis:

“I actually have no feeling in my penis. It sucks. Really bad. BUT, what I kept getting told by all the doctors is, sex is mostly in your head. Once I figured that out, it made it much better. Now, I have other areas that are hyper focused and I get pleasure from.

“My orgasms pre accident were SUPER fantastic. I was in excellent shape and had mastered controlling my orgasms from using muscle control. Those muscles are paralyzed now so orgasms are.. hard to describe, but not so great (but at least I get something). It’s mostly head now. I can feel the rush of chemicals in my head and I’ll get that slight body tingly feeling. Your question has been asked before, but I’ll add a little something extra to it. I just recently tried cannabis for the first time and while it helped my nerve pain in my legs some, it GREATLY improved the orgasm. I’ve since experimented (for science!) a few other psychoactive chemicals and 3 times now I’ve had orgasms that were as good as or even better than before my accident.”

As for whether or not he can ejaculate, well, titantool responds that while he can, “it’s not forceful like it used to be” and that “it just oozes out now.”

Can He Last Longer in Bed?

“My penis can still do the same and more than previous,” he writes in a comment. “The main thing being [I] can last an eternity.”

And for those quick to recite that classic line from the Viagra commercials about erections over four hours, titantool maintains that he’s a special case.

“The damage from having an extended erection is to the blood vessels,” he explains. “Those have been removed from me so I don’t think it’s an issue.”

Would He Use His Bionic Penis in “Cyborg Porn”?

SO glad you asked this!! Honestly, I’m REALLY surprised no porn actors already have one. I’ve heard the first test to being in porn is being able to have a full erection on demand. With this, DONE! You can get it SUPER hard, lasts as long as you want, and you would NEVER know on camera that you had one. Logistically for me, getting my wife’s permission. But also, I can’t control my orgasms anymore so I would have to act that part out (I took some acting classes in college). Right after I came on here to do this AMA, I saw that porn star Alexis Texas was just wrapping up her AMA. If I had been a bit earlier, maybe she could’ve told me if I have the right stuff for porn.

Does He Feel Differently About His Manhood Now?

Redditor techiebabe asked this provocative question:

“Final question, is your penis tied to manhood, macho status, etc.? As a woman I think I understand, but I’m curious to know to what extent it really does matter and affect you, behind closed doors when you have nothing to prove to anyone else.”

In response, titantool offered an honest analysis of what his new penis means to him:

“Without a doubt! It’s what made getting the surgery in the first place so difficult. Even though I couldn’t get/maintain an erection, the thought of having a device shoved inside my dick was severely distressing and felt like I was losing my manhood. I talked to a lot of men on forums that reported how satisfied they were with theirs. That helped, but I finally got to a place where I had exhausted all options and it was time to do it. After my 6 week follow up and he told me to go home and test drive it, I knew I had made the right decision. It was super awkward at first, but now it’s just a part of me and I embrace it (so much that I’m sharing my dick pics with total strangers!)”
